Our TCU upgrade will provide faster gear shifts, reduced slippage and enhancement of torque limits permitted by the Mercedes original program. The shift quality improves dramatically and our upgrade offers a more manual mode than the standard software.
Customers based abroad can send in their TCU's to us for upgrading. The upgrade process takes 1 to 2 days and the TCU is returned on a DHL Express Service.
